IDENTIFICATION OF NEW PRODUCTS OF S-AMINOETHYLCYSTEINE KETIMINE AUTOXIDATION

In continuation of a previous work (Pecci et al., 1993), dedicated to the detection of the autoxidation products of S-aminoethylcysteine ket imine (AECK), we give here data for the identification of ,3,6,7-tetra hydro-4H-[1,4]thiazino[2,3-b]thiazine, thiomorpholine-3-one and 5,5', 6,6'-tetrahydro-2,2'-dihydroxy-3,3'-bi-2H-thiazine among the products of AECK autoxidation. Identification has been done on the basis of mas s spectrometry and NMR spectral analyses of the isolated products.
